【摘要】 根据弹性力学平面问题的基本理论,采用半逆解法,求出了两端固支梁在集中荷载作用下的应力和位移多项式解,并与材料力学解进行了比较,说明了材料力学解的精度和适用范围,可供工程结构设计和弹性力学教学参考.
【Abstract】 By means of the basic theory of plane problem in elastic mechanics and by using semi-inverse solving method,the stresses and displacements of the beams fixed at both sides under the concentrated load are calculated.The results are compared with the solutions of the mechanics of materials.The precision and applicability of solutions of the mechanics of materials are discussed from above solutions.The results may be helpful for structure design and elastic mechanics teaching.
